1. Dab tsi yog qhov kub tsis kam ntawm Q215 welded kav?
Q215 welded kav muaj qhov kub thiab txias nyob rau hauv ib puag ncig kub (0-100 degree). Lawv tuaj yeem siv rau kev thauj cov kua dej hauv chav tsev kub lossis kub qis, tab sis lawv tsis haum rau qhov chaw kub kub (siab tshaj 300 degree), vim tias qhov kub thiab txias yuav txo tau lawv lub zog txhua yam.
2. Q235 welded kav puas tuaj yeem siv rau hauv siab -kev siv kub?
Feem ntau, Q235 welded kav tsis haum rau ntev - siv nyob rau hauv siab - qhov kub thiab txias (siab dua 350℃). Ntawm qhov kub thiab txias, lub zog tawm los thiab lub zog tensile ntawm Q235 steel yuav txo qis, ua rau cov yeeb nkab deformation lossis tsis ua haujlwm. Rau siab -kev siv kub, tshwj xeeb kub- cov qib steel resistant yuav tsum tau xaiv.
3. Qhov ntsuas qhov hnyav rau Q195, Q215, thiab Q235 welded kav yog dab tsi?
Cov mis laij lej hnyav rau welded kav (ib meter) yog: Nyhav (kg / m)=0.02466 × (Sab nraud txoj kab uas hla - Phab ntsa thickness) × Phab ntsa thickness. Cov mis no siv tau rau tag nrho peb qib, vim lawv qhov ceev yog qhov zoo ib yam (li 7.85 g / cm³).
4. Dab tsi yog qhov sib txawv ntawm txoj kab uas hla ntawm Q195 welded kav?
Qhov sib txawv ntawm txoj kab uas hla ntawm Q195 welded kav yog 15-200 hli, uas yog siv rau cov kav dej me me hauv kev lag luam hauv pej xeem thiab lub teeb, xws li cov kav dej thiab cov kav dej.
5. Vim li cas Q235 yog qib siv dav tshaj plaws rau cov kav dej welded?
Q235 yog qib siv dav tshaj plaws vim nws muaj qhov sib npaug zoo ntawm lub zog, ductility, thiab tus nqi -kev ua tau zoo. Nws ua tau raws li qhov yuav tsum tau muaj ntawm feem ntau nruab nrab thiab qis -load daim ntawv thov, muaj qhov zoo tshaj plaws weldability, thiab cov nqi raw khoom qis dua siab -lub zog steel, ua rau nws yog thawj qhov kev xaiv rau welded yeeb nkab ntau lawm.
